AUTOVOBLE DIRECTION SIGNAL."

Specification of Letters vPatent. Patented July i8,

Application filed. August 29, `1921. Serial'o. 496,500.

To all/whom t may concern: v *i Be it known that l,` @SGAR LM. l/YEST, acitizen oit the United States, residing at St. laul, in the county olRamsey and State oie liiinnescta, have invented a new and use iiulrutomoliile Direction Signal, oflwhich the rollowing` is aspecilication.

lsiy invention relates to direction signals for vehicles,` particularlyautomobiles; and the object is to provide a device which is of light,`compact and durable construction, easily operated and readily mountedon any type oi vehicle withinV easy reach of the driver.

"if he above object l attain by' the construction illustrated in theaccompanying drawing, inv which;

Figari is a top view of my device attached to the iframe oi? anautomobile wind shield.

l11 ig. 2 is a iront elevation ot' 1, omittineone shield memberv andshowing' the signal arm (in dotted lines) in extended po#y sition. y n

Fig. 3 is an elevation oi two of my devices mounted on opposite ends ofAan automobile wind shield approximately as they would appear viewed fromthe drivers seat.V

Figi: if is an enlarged sectionalelevation asonline 1 4 in Fig..2.7

Referring; to the drawing' by reference'y numerals, 5 designates theupright frame bars and' G the glass of an automobile wind shield. 7 isthe so-called instrument board located below the wind shield and infront ot the driver7 and 8 (shown dotted in Fig. 3) is the steering'wheel'in approximately correct position with relation to other parts ot'an automobile above described.

My device consists of a light 'frame comprising; two vertically disposedspaced plates 9. 10.r ot which plate 9 preferably holds a irror orreflector 9", while 10 has a bracket extension 11 with pertorations forinsertion of screws 12 to secure said fra-meat any desired height onupright 5. rl`he'plates are connected rigidly by bolts 13 extendingthrough intermediate spacers 18X. The space between the plates containsvthe main working' parts of my device constructed and operated asfollows:

rlhe signal arm of my device is a hori Zontally proiected device formedon the klazytonrrs principle normally in folded or retracted positionbetween the plates 9 and 10. lt comprises a series oi flat, preferablyS- shaped cross bars 14, 14EL pivotally connected at their crossings ltband'V each pair o1 such I cross arms pivotally connected to the nextpair at their ends as atlic. The extreme outer pair of such cross kbars14 and 11i, have their free outer ends 15 iormed in triangular shapetomake the appearance of an yinto the space between plates 9 and 10 bysimply pushing or pulling on two links 16 pivotally .connected `withtheir outer ends to the adjacent rcross bars 14, 14a; `'the inner endsof links 1G being` brought together and pivotally connected in across-head 17. Said links 16 are slotted as at 16X intermediate theirends,` each slot being engaged by a stationary pin 18 secured in, plate10 (see Figs.`

2 ande). Y Said stationary pins act as `tulcrums for the links making'them beam levers spaced from plate 10 by spacers 19 corre- 'spending toheight of inner ends of links 16 where the latter are pivoted incross-head `(see Fig. et). i

@ross-head 17 has an inwardly projectingr horizontal rod member 2Oyfuided in a bearing' 21 and the cross-head itself is guided in astraight channel 22 secured to plate 10 or lormed integral therewith. Acompression coil spring 23 on rod20, between bearingr 21 and cross-head17 tends to keep the signal arm in retracted position as in Fig. 2l. Aneyelet 24 at the inner end of rod 2O provides means for operating therod endwise against the force of the spring 23 and this is preferablydone in the following' manner.

ln Fie'. il l have shcnvnl two of my devices on an autowind shield forright and left hand.signallingN operated by means or levers 25 pivotedin brackets 26 secured on the instrument board or other convenient placein front/ofthe driver. One end of each lever is connected with a cable27 inserted in a yguiding" conduit 28 which extends horizontally to thevertical frame member 5.

to indicate that he is'abont to make a left turnj he pushes the leftside lever 25 to the lett, either by hand or with his-lett knee,`

to approximately the position shown dotted in Fig. 3. The opposite endotsaid lever pulls cable 27 which in turn pulls rod 2() (see Fig. 2) teapproximately position 20X, siniultaneously slidingerOss-head 17 towardbearing 2l against pressure of spring 253.'

The sliding ot cross-head i7. pulls at the inner ends ot linlrs` whichcausesv the outer end te niove outwardly or toward the lett as in 2. Themotion ot the links 1G is instantly transmitted through bars 14 and1+ithrowing them outwardhorizontally as indicated in dotted lines .inFig. 2 and forining a. comparatively long and rigid arm with an arrow`like point projeeting to the lelitp-i brignt coloring on this extensionarm will inalre it appear quite prominently and can be readilyseen bydrivers of `other automobiles on the same road. The pres` sure ot.spring 23 causes the retraction of the signal arm to its originalposition when lever 25 released. "lo indicate aright turn .the righthand signallino` device is operated in the same manner as the left ex@eeptthat right `hand -lever 25 in liront. ot driver is pushed to theright. y

My device isilnounted` at height Corresponding to the heigh-tot thedrivers head, with the .mirror side toward theY rear, said mirror takingthe placeoilfthe so-ealled re-y flectors ordinarilyused on `many oarsand enabling the driver to tell at a glance xif other ears are followingnear `enough tov require theuseoi the-signalling device `when he intendsto malte, a turn.
